    "(...) macroscopic variables, which represent the collective motion of a large number of microscopic particles (...)"

    Seems I can find some definitions. Is that specific enough?

    Macroscopic Variable A measurable quantity used to describe the gross state of the system. It depends collectively on the behavior of all the atoms and molecules. These are also referred to as thermodynamic variables. a macroscopic variable may be constant over time for a system, yet there will almost cetainly be continous activity at the micro level.

    anything else i can add...or does this make sense
